[0002] Gear grinding and polishing plays a vital role in the gear manufacturing process. During long-term mechanical operation, the surface of the gear may lose its flatness due to wear, which will not only cause uneven pressure distribution on the tooth surface, but also reduce the efficiency of gear transmission.
